Creality Dual Extrusion Board Firmware | V2.X Board
Do you have a Creality machine with the Dual Extrusion board and want a stable firmware with the latest features?
What is a “2560” Board?
These are the boards with the Atmel 2560 CPU on them. These boards came with the bootloader preinstalled and these machines typically have a filament sensor preinstalled on the machine (with the exception of the CR-20 and CRX). The current versions of these boards have a number of V2.X on them and the original ones had no model number on them and were green or black in color.

Board Limitations Note: Due to the design of the Creality boards with TMC drivers Linear Advance will probably not work correctly. The feature is available but use at your own risk.
Touch Screen Models Note: The CRX and Ender 5 Plus all came with factory touch screens that are not able to be controlled by Marlin. These printers are only compatible with this firmware when they have been upgraded with our LCD conversion kits.

1 – Printer Board Firmware Update
NOTE: These printers update over the USB cable from your PC to the printer. Make sure to have a USB cable ready.
1.a – Download the firmware
1.b – Extract the files to a folder on your computer
1.c – Open the folder labeled “Firmware” in VSCode
1.d – Open the Configuration.h file that is located under the “Marlin” folder on the left side of the VSCode screen
1.e – In the Configuration.h file, uncomment (remove the 2 / in front of #define) the printer model line for your machine in the “CREALITY PRINTERS 2560 CPU BOARD” section and any other options you are going to use in the firmware.
Read through the firmware for the dual extruder board options for your machine you are installing it on.
1.f – Click the ✓ at the bottom of VSCode to compile the firmware. The firmware will compile. This may take 1-5 minutes depending on the speed of your computer and internet connection
1.g – If the build succeeds plug in your printer to your computer with the USB cable.
1.h – Now click the arrow (right pointing) to upload to the printer board.
Make sure ALL slicers or other programs that connect to your printer board are CLOSED before trying to upload to your printer.
Please note that on machines with multiple COM ports you may have to select the COM port manually. Please see our VSCode COM port selection article to see how to do that.
1.i – The firmware will upload to the printer board over USB.
DO NOT UNPLUG THE PRINTER OR RESET YOUR COMPUTER.
Interrupting the flashing can “brick” your board and if this happens you will need to reflash the bootloader with a programmer (like an Ardiuno UNO) before you can flash again.
1.j – When the printer boots you will see the TH3D logo on your LCD. Make sure to reset your EEPROM on your printer after flashing any firmware. You can do this from your printer LCD or by sending a M502 followed by M500 with your favorite Gcode sender application.
